摘要： This application discloses a wireless power supply apparatus and a wireless power supply terminal, and relates to the field of wireless power supply technologies. The wireless power supply apparatus includes a controller, a beamforming module, and an antenna array. When direction finding information is obtained, the controller determines an electromagnetic wave transmission direction, and transmits information about the transmission direction to the beamforming module. The beamforming module aggregates energy of electromagnetic waves corresponding to a plurality of radio frequency signals to the transmission direction. The antenna array receives the direction finding information, and transmits the electromagnetic waves. The wireless power supply apparatus can automatically determine a direction of a wireless power supply terminal relative to the wireless power supply apparatus, to improve efficiency of power supply, thereby avoiding a manual measurement operation, and facilitating deployment, and can simultaneously supply power to a plurality of wireless power supply terminals.

摘要： The disclosure is concerned with a receiver module (21) for wireless power transmission. The receiver module (21) comprises at least three transformer circuits (T) for transforming a received power transmission signal (Vin) into a supply signal (Vout) for a connectable energy storage device, such as a battery (23). The transformer circuits (T) are connected in series on a primary side (I). Due to a respective coupling capacitance (Cps1 to Cps4), each of the transformer circuits (T) may be unbalanced with respect to their output signals (V1, V2, V3, V4). To balance the output signals (V1, V2, V3, V4), which are used to provide the supply signal (Vout), at least two bypass devices (B) comprising at least one bypass capacitor (Cpp1, Cpp4) are connected in parallel to the first and last of the transformer circuits (T) in the serial connection.

摘要： An apparatus is disclosed for a hybrid foreign-object detection and position system. In an example aspect, a foreign object detection (FOD) system of the base power-transfer system detects a passive beacon of an electric vehicle power-transfer system based on a beacon loop of the passive beacon overlapping an array of FOD sense loops effective to cause a change in impedance or admittance of one or more of the FOD sense loops. In aspects, the impedance reflects a modulation signal from the passive beacon. A position detection system integrated with the FOD system determines a passive beacon response in the input data based on the modulation frequency from the passive beacon. Then, a position of the beacon loop is determined relative to the array of FOD sense loops using a result of the passive beacon response canceled from input data.
